some ppl are just so sure tt what they r doing is correct, that they are infallable, i really wonder, what drives their belief? how did they find so much confidence in themselves? that they are always right and everyone else who happens 2 not agree with them must b in e wrong? i, for one, can never summon up e courage or confidence in many situations 2 say tt i m 100% correct..there's always this doubt, what if i'm wrong? haha, as it has turned out many times..i just wonder, do these ppl just have a big ego or what?
